Improvements in Closure-Locking Means' for Gssltetorts, of whichthe'following is a. specification.

The operation of coul gas generating op pnratus iis heretoforeconstructed is sometimes interrupted ond seriously retarded byprernntiirely opening :t retort. TWith the front and rear closures underseperate control, and with the operatives necessarily seperated bythelength or depth ofthe bench, communication between them cnnnot bereadily maintained, and even with every precaution as to signaling' fromone to the other, the Jfallible human element has always been presentand has resulted in more or less frequent premature opening of theretort, particularly Tait its rear.

One object of the present invention is to provide for'so controlling theclosures :it the front and rear ends of the retort that 'it isimpossible to prematurely open Y either closure, the errsngement beingpreferably such that oprning of the rear end closure is controlled oythe front end closure, tho opening movement of the letter effecting therelease of the closure et the rear end.

A further purpose is to so coordinate the, retort closures with theVvalve which con-v trols'communicetion between the retort and the stndpipe that the vulve is necessaril seated before either closure `een beopone eit er end of the retort in a vence of closcommunication with thegas otclre.

F ig. 6 is an elevation of the circuit interruptingmechanism Which operated by the charging Vclosure door, a. portion ofthe inolosing casing being renioved. Fig. 7 is n sectional elevation,taken on lthe broken lines 7-`7 of Fig. 6. Fig. 8 is a sectionalplan'taken on line 8-8 of Fig. 7. Fig. 9 is a detail View of the shoefor importing opening pressure to the circuit breaker. Fig. 10 1s asectional elevation of` the locking. mechanism for the dischargeclosure, toren on line 10--10 of Fig. 13. Fig. 11 is o sectional detailon line '11-11 of Fig. .10, and Fig. 12 is a vertical cross.- scctiontekenen line 12--12 of Fig. 10. Fig. 13 is :i plan View of the lockmech- :mism et the retort discharge, the upper portion of the inclcsingcasing being remoi/ed.

Referring to the drawings, 2 designates one of e series of retorts oi egas bench; 3 is the mouth piece :it its inlet or charging end or theretort, und 4. the mouth piece at its outlet or discharge end. Mouthpiece 3 is enlarged :it one side et 5 with port 6 thereof communicatingwith the gas o'- trike or Stcndpipc 7. Valve 8 for controlshaft 9 whichma be rotated in any suit-` able monner. This shaft carries the indexarm 10 which, when the4 valve is open as in full lines in Figs. l and 4,projects into the path of the swinging latch mechanism 15 for the frontend closure when the latter is in closure-confining position.l Thislatch` mechanism may servo to close the valve, movement of saidmechanism in a direction to release the closure serving to turn theindex firm 10 and thereby rock the shaft 9 and close the valve.

As illustrating anV embodiment of the present invention, the closure forthe charging end of the retort is indicated as 1,1 and its hingedbnr-like support as 12, While at the discharge end the closure bearsreenence numeral 13 'which is carried by hinged bar lai. The free end of bar12 isconined` by it laterally swinging hitch mechanism l5, 105

and e-similsr mechanism 16 performs the same function .tor bei' 14 ofthe discharge rlosure.

A horizontally swinging arm 17 controls the manipulation of bar 12necessary for releasing latch mechanism 15, and arm 18 similarlycontrols the discharge closure bar 14. When arm 17 is turned from theposition shown in Fig. 1, eccentric 17 at its pivoted end moves support12 toward closure 11 so that latch mechanism 15 may be readily turned torelease the bar, and eccentric 18 performs the same service for bar 14with reference to rear end closure 18 when arm 1S is turned intoposition for releasing latch 1G. Arm 18 is disposed toward the hingedend .of support 14 when said closure is closed, While at the chargingend the swinging' arm 17 for hinged support 12 is disposed toward whenclosure 11 is in closed position.

For so connecting the charging and discharging closures that the lattercannot be opened in advance of the former, a mechanism is interposedwhich at the charging end is operated by the movement of the hingedclosure support 12, and at the discharge end cooperates with swingingarm 1S, the latter being held locked as indicated in full lines in Figs.1, front closure has been opened. 'While there is no impediment to themovement of arm 17 of the charging closure from the position shown in F4 and in full lines in Fig. 1 to the open dotted position of Fig. 1,support 12 cannot be released from its latch device 15 until index arm10 is moved out of Way of the latter and this can only be accomplishedby closing valve 8 so that itis mechanically impossible to swing support12 to open position before closing the olf-take valve.

The mechanism for connecting the front and rear closures for insuringtheir opening in proper sequence may be variously arranged. As hereembodied that mechanism includes an electric motor device for actuatingthe discharge closure lock, together with a switch for the circuit ofsaid device which is operated by the movement ot the inlet or chargingclosure.

The lock device for arm 18 of discharge closure 13 consists of an arm 19which is forked at 20 to embrace arm 18 when thc latter is in closedposition, as shown in full lines in Figs. 1 and 10, arm 2O being securedto rock shaft 21 journaled in a casing 22 secured by bracket 23 to mouthpiece 4. Secured to shaft 21within said'casing is arm 25 which Whenraised holds arm 18 frein swinging outward into Ireleasing position. Arm25 is held elevated by the notched upright arm 26 of bell-crank 27, thelatter fulcrunicd at 28 in casing 22, with the horizontal' arm of thelever entered in a slot in core 29 of solenoid 30. Vith the solenoiddeenergized; its core drops by gravity and thereby moves and holdsbell-crank 27 in the full line position of Fig. 12 withits notchedvertical arm 26 beneath and holding raised the free end of the latter I2 and 10, until the 25. With the solenoid energized, its

core is elevated and bell-crank 27 rocked into the dotted line positionof Fig. 12, lthereby releasing arm 25 and permitting the forked arm 2Oto oscillatc in response to the outward `pull on theclosure unlockingarm 1S so that closure 13 may then be opened.

The energy for the controlled by a which extend to the fron-t of theretort and .into a casing 33 which incloses a circuit breaker. Thiscasing'may be secured by bracket 34 to mouth piece 3. lVithin the casinglead 31 is secured to contact plate 35, and lead to contact plate36.Plates 35 and 36 are adapted to be connected. by the circuit closing (orbreaking) arm 37 which coil 'pf solenoid 3() is near one end is mountedto oscillate on bolt,

38, with a spring 39 conned on the bolt and exerting pressure .on thearm to move it -into closed position. One extremity of arm 37 is inconstant engagement With contact 36, Figs. 6 and 8, while its free endcarries the rounded Contact shoe 40 for engaging econtact 35.

The circuit breaker 37 is engaged by the insulated shoe 41 carried bythe free end of 'arm 42. The latter is secured to shaft 43 Within casing33, and an arm 44 on said shaft at the exterior of the casing has itslaterally bent extremity 45 .adapted to be engaged by the swingingsupport 1 2 of the front or charging closure 11. When support 12 andclosure 11 are in retort closing position shown in Figs. 1 and 8, arm 44is pressed inward and breaker 37 is held in open position by arm 41notwithstanding the pressure of spring 39. But as soon as support 12swings into open position, arm 37 into engagement with contact 35 andcloses the circuit through leads 31 and circuit having leads 31 and fthe circuit Y spring 39 moves shoe y40 of 32. vThis results inenergizing solenoid 30,

and the upward movement 4of itscore tilts the bell-crank latch 27 andreleases the lock for arm 18 of the discharge end closure, whereupon thelatter may freely open. But I prior thereto the closure13 is heldsecurely locked and it is quite impossible to open it in advance ofopening the front end or charging closure 11. And opened untilcommunication is closed between the retort and off-take, it will be seenthat the sequence of operations. is relieved of the uncertainties ofhuman control, the several elements heilig so connected as to inf suretheir operation in proper sequence.

When sealing up the retort, the rear closure 13 may be closed eitherbefore or after the front closure 1l.
